Abstract
A method of memory sharing implemented by logic of a computer memory control unit, the control unit comprising at least one first interface and second interfaces and is adapted to be connected with a main physical memory via the first interface, and a set of N≧2 non-cooperative processors via the second interfaces, the logic operatively coupled to the first and second interfaces. The method includes receiving, via the second interfaces, a request to access data of the main physical memory from a first processor of the set; evaluating if a second processor has previously accessed the data requested by the first processor; and deferring the request from the first processor when the evaluation is positive, or, granting the request from the first processor when the evaluation is negative.
